2N-Reactor, ultra-compact (EPD 187 kW/Tile)

Post by VampireSilence »

Hello everyone,

after many months of tesselating my world with solar panels, i finally brought myself to take a look at nuclear reactors.

I was annoyed by the space solar panels take, which i usually had to clear from biters etc. before. So i spent several days with fiddling around with nuclear reactors, debugging, reconstructing and so on and ultimately came up with this design. My goal was to improve as many aspects as possible that annoyed me regarding solar panels. I guess its useful anywhere between lategame and megabases.

Please tell me if you like it and what i could improve any further. :)

Blueprint:



Features:

- stripe design
- ultra-compact layout (5,34 Tiles/MW)
- infinitely extensible in both directions
- even 2D-tileable, but tricky due to the massive stripe width
- 367 to 400% efficiency (asymptotic increasing with number of reactor stripes)
(e. g. 383% efficiency at 2x12 reactors, 392% efficiency at 2x24 reactors and so on)
- energy production density: 187 kW/Tile
- density increasable by removing the outer roboport-row or the tanks at the ends of the stripes
(but i felt like having a minimal amount of tanks is better)
- NO need for fuel moderation, reactors never reach 1000 °C under full load
- blueprint grouped by 2x6 reactors (representing 6 stripes)
- still possible to end the lane at any stripe you like
- fuel-fed by robots (easy convertable to belts *)
- water-fed by direct pumps (easy convertable to an external pump system **)
- beautified wiring
- completely buildable by robots, due to integrated roboports
- shared/balanced ressources between stripes: heat, steam, electricity (obviously)

*, **: you will find 2 rows at each side of a stripe with accumulators. You can swap those for a belt and/or pump system setup, in case you dont like robots and/or dont build it at water using landfill

Important: Electricity of top- and bottom side of a stripe is NOT connected by itself. Connect each half seperately or place a single pole next to the reactors at any end of the reactor chain to connect them.

How did you get your figure for energy density? By my count, your design (excluding the outer roboports & power) is 334 tiles wide by 60 long, for a total area of 20,040 tiles. It outputs, even in the ideal of an indefinitely tiled design, 3840 MW, which comes to ~191KW/tile. I think you might've forgotten to account for the mirrored side.

You are right, plus i calculated it before adding the outer roboports, which adds another unconsidered 5 tiles in height. I corrected all those numbers and updated my post. Thanks for pointing this out to me.

Never assume it's running on full load 100%.

Add some logic, does not need to be very complex, just replace 1 roboport or two. Sadly I can't tell you how exactly because I'm not at my home now, but it's possible to make a very compact circuit, smart enough to start itself without human interaction after bot building.

In this screenshot download/file.php?id=63990 every single reactor has it's own load control + some indication lights + backup power in the inner circle

Ok, do you have some blueprint you could send me? Then i try to adapt it to my reactor.

I also have 2N-design which is easily expandable. It's based on another example I found on this forum, I just simplified it a little bit. You need to build this on a long lake. This design is even more compact and achieves 219 kW/tile. This is possible as the outgoing strips are not as wide as a reactor. So you combine 2x6 reactors with 5 of those strips, and you get an almost perfect ratio.

Reactors + heat exchangers

The whole turbine setup:

It does not have any buffers or controlled shutdown to optimize fuel usage, it just runs through. As the purpose of such a reactor is typically to provide for a megabase, I don't really care about the usage of Uranium which I have in massive amounts, but the lot more limited supply of UPS. And this buffer mechanics are typically pretty bad for UPS.
